This behaviour is definitely not normal.
I just had another look into the source code, and on second thought,
there might be a chance that the test for a non-empty dir is skipped
and the dir is renamed instead.
The only problem is that: Even though I see how I could potentially
enforce the situation, I fail to reproduce it. Can you explicitely show
an ls of the dir and an strace of an rmdir which succeeded to rename the
